This URL provides the access to the most recent output from the database. The output is being overwritten as often as possible.

This data set was output from J-CORES database by using its complete Bulk Export function Version 1.9.9 from 2018-01-23T17:20:36Z till 2018-01-23T17:20:53Z.
The specification of the outputs is available to be referred.
Bulk Export gives a file bulk.csv
with various attachment files (e.g. image files).
Files bulk-something.csv are generated
by picking some kinds of data from bulk.csv.
Files something.zip consist of
bulk-something.csv and related attachment files.
Files bulk-something.csv are in character encoding UTF-8 with line ending characters CRLF.
The database has a flexibility to store numerical/text values and attached files for user-defined parameters,
which are output into User-Defined Parameter column group in bulk.csv.

Parameter definitions

The user-defined parameters are listed with their definitions as the followings.

X-ray CT scanning

X-ray CT scanned images for core sections. The right-handed coordinate system is
applied to each core section as the followings. Y axis is from the working half
toward the archive half. Z axis is from the core bottom toward the top. (x, y,
z) = (0, 0, 0) at the center of the top of the core section.

X-ray CT scanning::coronal image

The cross section at the boundary of the working and archive halves of the core
section, looking the archive half side. In other words, the x-z plane (y = 0),
looking to the negative y. The image is created by compiling the series of axial
images, at each of which z is a constant. The file is formatted in DICOM.

X-ray CT scanning::top margin [pixels]

Height of the margin at the top of the image. Not always integer.

X-ray CT scanning::each side margin [pixels]

integer.

passes through at the split point between working and archive halves).

archive halves). P-wave pulse which is an ultrasonic compressional pulse
generated by a piezoelectric crystal is 230 kHz.

MSCL; section::natural gamma radiation: detector set #1, 80 mm [CPS]

Counts per seconds of detected gamma ray photons. This count is a total of four
scintillation detectors. Each of the four detectors is combined with a
multichannel analyser. They are attached in a cross shape on a central lead cube
which is on the track of the Multi Sensor Core Logger. Serial number of the each
detector is; the upper side (a detector at the direction of 12 o'clock from
the view in the core movement direction) is 04L033, the right side (at 3
o'clock) is 04L028, the lower side (at 6 o'clock) is 04L034, and the
left side (at 9 o'clock) is 04L041. The aperture of the central lead cube
